Sentinel Surveys 1995-2005: Catch per Unit Effort in NAFO Subdivision 3Ps

By Maddock Parsons, D., and R. Stead

Abstract

Sentinel enterprises continued to collect catch rate and biological information on inshore 3Ps cod resources in 2004 and 2005. Gillnet catch rates (weekly average number of fish per net) in the most recent years remained low compared to 1996-1998 catch rates. Catch rates in small mesh gillnet remained low. Length frequencies of cod caught in small mesh gillnet showed fewer fish at the two size modes (36-44 cm and 52-56 cm) that this gear catches since 2000. Linetrawl catch rates (weekly average number of fish per 1000 hooks) increased from 2000 and showed an increase in the number of fish at the 44-54 cm size range from 2002 to 2004. In 2005, preliminary linetrawl catch rates are the lowest in the time series.
